Error of cannot find FacesContext

[Robert Strong]

hi, I'm using JavaServerFace on Weblogic8.1 SP3, the web application seems to be deployed successfully. But everytime when I request a JSP with JSF component, it'd throw such error:

javax.servlet.jsp.JspException: Cannot find FacesContext

any help appreciated!!

Most likely, it happens if you call jsp directly without using the servlet mapping. There is a number of other issues you can check including the servlet specific ones. See also: http://forums.bea.com/bea/message.jspa?messageID=202173921&tstart=0

Seems you are not going through FacesServlet.
See this thread if it can solve your problem.

Hi, I have this problem in Tomcat 5.0.28, but I found something may be that will help you. In my web.xml, I had defined this before ...
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
......
<welcome-file-list>
<welcome-file>faces/hello.jsp</welcome-file>
</welcome-file-list>
I can see something when I use http://localhost:8080/faces,but had problem to view like http://localhost:8080/MyTest.jsp, so I changed MyTest.jsp to MyTest.jsf, then everything run well.
I found in my c:\tomcat\conf\web.xml has this:
<!-- The mapping for the JSP servlet -->
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.jsp</url-pattern>
</servlet-mapping>
so I guess when you run http:/xxx/*.jsp, it will forward to org.apache.jasper.servlet.JspServlet not javax.faces.webapp.FacesServlet,
so it throws "could not found FacesContext excetion".I thing that it the same in WL 8.0, maybe you can try it.
